1
Q
How can you tell if a data set represents a Quadratic Function?
A
The x values will be equally spaced and the second differences will be constant.
2
Q
What is a Quadratic Model?
A
A quadratic function that represents a real data set.
3
Q
How do you get a Quadratic Equation that fits three original points?
A
You put in the standard formula (f(x)=ax^2+bx+c) and substitute the values and solve.
4
Q
How do you make a Quadratic Model?
A
You solve for the points and graph them/solve.
